the invention n'iay have other applications and uses.

In marking machines as heretofore constructed for use with measuring machines some of the operating part-2 have been so cont; structed as to permit of an amount of lost motion which resulted in undesirable vibration and even backlash in the parts. Furthermore, in certain prior constructions the capacity of the marking machine was limited :1 to the marking or printing of numbers within the range of the dial and pointer of the measuring indicator mechanism a determined by one circuit of the pointer over the dial. For instance, the marking machine of such prior 2 1 constructions would not operate to mark the number d0 on a piece of work if the pointer in its circuit once around the dial could indicate at its maximum the number only.

It is an object of the invention to provide a a simple yet durably constructed machine for the marking of pieces of material which will be more positive in its action and, therefore,

more accurate because free from backlash and undesirable vibration of the parts. It is a 5 further object of the invention to provide a marking machine of greater marking range than tl ose heretofore provided for use with leather measuring machines, while at the same time minimizing the number of parts of the machine.

To these ends and in accordance with im portant features of the invention there is pro vided, in an area measuring machine, means under the control of the operator for condi tioning the marking means to vary the norand selecting movement of the marking means so as to widen the range of marking 0pcrations. In the ill ustrated construction, operation of means for selecting proper type blocks to mark the material in accordance with a measurement by the measuring means is controlled to take place automatically after the marking means has been rendered capable of a wider range in marking operations than that indicated by the pointer in a single circuit of the dial in the indicator means of the measuring machine. Convenently, a manully operable member is employed for adjusting preliminarily a part of the type block select ing means with respect to a controlling cam for the marking means so that the preliminary adjustment is added to the movement of the selecting means secured as a result of the power operation of the marking means. As illustrated, a plurality of plungers and a plurality of levers connected each to its respective plunger serve as connecting means between the controlling cam of the marking means and a plurality of sets of type selecting or setting means by which the latter upon operation are moved to place one block of each set at atime in selected position. In one of these connecting means the lever provided is a two-part lever connected with it associated plunger and adapted to be adjusted by the described manually operable member for setting one part of the lever in selected relation with respect to the other part whereby the associated plunger is preliminarily adjusted with respect to the controlling or setting cam for the marking means in an advanced relation thereto, the advance movement of the connecting means thus secured corresponding to the amount of the measurement of the material in excess of that ind1- cated by the pointer of the indicator means 1n a single circuit over the dial of said indicator.

Another feature of importance relates to improved means for selecting the type for printing or marking of the material wherein ronnectioi'is between a selecting means and a controlling or setting cam of the marking means comprise plungers, and levers directly connected thereto and adapted to move substantially as a single unit with the plungers thereby minimizing vibration or backlash in the connections through which the selecting means are controlled to move to operative position the type blocks utilized in printing or marking on the piece of work.

Other features of the invention relate to improved means for applying ink to the selected type blocks as a preliminary to a printing or marking operation. In the illustrated construction this means comprises an oscillatory member yieldingly connected to an inking roll and positively operated to travel back and forth in a predetermined path to pass the inking roll over the type in marking position only, during oscillatory movements of the inking roll between ink-receiving and ink-applying positions. Preferably and as shown, the inking roll during its oscillation about its axis moves in a straight line while applying theink to the type block.

These and other features of the invention will be described in detail in the specification and pointed out in the appended. claims.

Figures 1, 2,2 and 8 are drawn to a smaller scale, and Figures 9 and 10 to a larger scale, than Figures 3 to 6, and like parts are designated by the same reference characters throughout the drawings.

Referring to Figures 1 and 2, the type setting means shown therein comprise slidable pli-ingers 1, 1a and 1b, and respectively corresponding levers 2', 2a and 2b freely mounted on a carrier shaft 3 rotatably supported in end frames 4 inwhich themain portion of the stamping mechanism (hereinafter described) is mounted. The plungers are jointed by pin and slot connections to the levers the depending arms of which latter constitute stops or abutments for engagementselectively by a series of projecting pins 5 disposed in the form of a spiral or volute in the usual manner in corresponding sprocket disks 6, around which character carrying member or type eledisks 6 to initial position.

ments 7 on flexible carriers 7 b are passed and which are frictionally and rotatably driven while supported on a shaft 8. Reading from left to right in Fig. 2, the type elements 7 carry numbers for the tens, the units, and the fractions columns, respectively. The shaft is driven first in the direction of the arrow Fig. 1 to bring the yieldingly driven disks 6 into set positions as determined by pins 5 in contact with the depending arms of the levers 2, 2a, 2?). Subsequently the shaft 8 is rotated in the opposite direction to return the Upon reference to Fig, 2 it will be observed that the disks 6 are tightly pressed toward each other, and against washers (one of which is shown at 66 keyed to the shaft 8, by means of springs 6a.. Each disk is thus frictionally driven and may be stopped independently of the others by a lever arm acting on one of the pins 5.

For a more complete disclosure of the driving means for the type disks reference may be had to United States Letters Patent No. 1,17 3,312 granted Feb. 29, 1916, upon application of G..A. Schettler. In the present arrangement, each of the levers 2, 2a, 2?) has upon it a weighted arm 9 so that when required it can be turned to bring the free end of its depending arm into position to act on the appropriate pin 5 inthe adjacent disk 6. The turn ing movement of each lever 2,. 2a, 2b is con trolled by its associated plunger 1, 1a,. 1b which is operated by the corresponding cam section 10 of a stepped disk 10c arranged to turn with the indicator pointer of a measuring machine (not shown) with which the marking mechanism is associated. For a more complete disclosure of the construction and mode of operation of the cam disk 10c, reference may be had to United States Leters Patent No. 1,114,917, granted Oct. 27, 1914, to G. A. Schettler. I

Since the aforesaid levers 2, 2a, 2b are freely mounted on the shaft 3 for movement to operative position, means are provided for holding said levers and their associated plungers 1, 1a, 1b, in the normal inoperative position, for freeing them for movement to operative position, and for restoring them to initial position. To this end the boss of each lever 2, 2a, 26, may have circumferential notches or gaps 11 (see also Figure 3) formed in one end of the boss for engagement by a pin 12 fixed radially in the shaft 3 which latter is rotatable in the direction of the arrow (Figure 1) to free the levers so that they can be turned by their weighted arms 9 until an rested by the plungers 1, 1a 1b, the shaft 3 being rotatable in the reverse direction to restore the levers 2, 2a, 2b, to and hold them in inoperative or initial position. The notches o-r gaps 11 in the lever bosses are made long enough to allow the levers 2, 2a, 2?) sufficient free movement to take up the various positions determined by the plun'gers 1,1a, 1b.

It will be understood that each of the disks (3 is arrested by the contact of one of its pins 5 with the free end of its associated lever 2, 2a, or 27), and that such disks, when arrested, bring the required types into posh tion for subsequent printing or marking o the meastnenient upon the material. In this connection, it is to be understood that the dish 100 with its cam sections moves with the pointer shaft 12aof the indicator 73 mounted on the frame of the combined marking and measuring machine, and that the greater the movement oi the disk 100 the greater will be the movement of the disks to bring the higher-numbercd type into place to stamp the appropriate characters on the work. in order that the various types, i. those of the dil'l'erent elements which correspond, for instance, to the units and tens columns, may be properly aligned, provision is made tt'or adjusting the levers 2, 2a, 26 on the carrier shaft 3 so that the position of arrest of any disk 6 can be moved forward or backward as may be required. To this end each 1e or instead of being;- mounted direetly on the shaft 3, is mounted upon an eccentric bushing 13 (i '1 and which is free to turn on the shaft. The lever is fastened to the bushing by a set screw (not shown) or other suitable means, and the bus-hung has knurled flange 13a to enable to be turned by hand in the lever after SlRClQHlllg the set screw. The said bushings are made shorter than the lever bosses so as to avoid the radial pins 12 but if desired the bush-1 e; may be madeas long as the be. and have corresponding notches or gaps formed therein to accon'imodate said pins. it further lever 26, (Figure 2) tori'ned without a depending arm but mounted and operated in a manner similar to the other levers 2o, 2?), is provided on the shaft 3 and connected with it is a plunger 10 titted with a pawl ii for engagel'nent with teeth 10o on the periphery of the stepped disk 100, when the levers are freed by rotation oi the shaft 3 as previouslydescribed, to lock said dist; in the type selecting position. The atorcsaid plungers l, 111, it), may be slidably supported by a bearing 16 mounted on cross member l? connecting the end frames l, and the pawl may be pivotally carried by an arm 18 extending from the said hearme.

The carrier shaft 3 may be operat cam or other means. Conveniently sa has an n 19 (7r 1g. :last thereon and con-- neet d by means of a linl-c to a bell lever ill which is tulcruined at .2160 on of the end trainee l: l fitter with a c roll 2:2 for ac uation bllQ re piired time if r "i n Q? in on the main shaft 16 of (M.

the stamping}; mechanism, the Wei e p 1 th asastance oi? a spring (not to keep i re roller 22 on the cam 23. In this way the 02111123 operated in properly timed relation serves to move the levers 2, 2a, and 2b to lock the type disks 6 in selectedpositions and subsequently to release the same and move the levers back to initial position.

It will be understoou that, as the type setting mechanism of the marking means is controlled by the measurement indicating means (including the pointer operating means) of the measuring machine, appropri ate types will be brought into position for use in accordance with the measurement indicated. However, in certain prior constructions, when a skin, leather or other material having a greater superficial area tl an the maximum provided for on the dial was put through the measuring machine and the pointer was consequently caused to make more than one revolution in which case the operator could by calculation tell what the total area was) the types of the stamping mechanism instead of being set to the total were only set in accordance with the actual position of the pointer since it was the position of the pointer which determined the setting of the types. For example, if the dial were divided and marked to indicate a maximum of feet and material having an area of feet were put through the measuring machine the pointer would. make one complete revolution and part of another stopping at the 10 mark. Now theoperator, knowing that the pointer had made a complete revolution would. add 30 (this being the dials maximum) to the number indicated by the pointer and would thus obtain the total measurement, but the types for stamping the measurement upon the material would be set to show only 10. To overcome this disadvantage and enable the stamping mechanism to be used to mark the correct measurement upon the material in cases where the material measured exceeds in area the maximum provided for on the dial, the present invention provides means whereby the types can be advanced or adjusted to compensate for the difference.

As regards the means adopted for determining the position oi the tens type disk 6 in accordance with i'neasurements which are in excess of the capacity of the dial as previously explained, the simplest way is to advance the tens type dish 6 one or more figures as may be required. For instance, by adjusting the tens type disk 6 one or more figurcsthe prc' '1' iry complete rotation of the pointer can be provided for and the fine Lulicatin position of the pointer will determine the i rther advance of the tens type to give a correct setti in accordance with the actual area measured.

Under ordinary circumstances it the dial pointer moves to 25, the tens types disk 6 is subsequently arrestedwith the figure 2 in position for use. Now suppose the dial 73 of the measuring machine indicator to be calibrated to a maximum of 30, and it is desired to measure skins or material exceeding this amount by say another 10 or 20, then by advancing the tens type disk 6 three figures the additional amount will be provided for, and

when the pointer stops at lO or on the dial after having made a complete revolution, thetypes of the stamping mechanism will, when this mechanism is subsequently used, be set to mark a measurement of 4:0 or 50 as the case may be. The means for quickly and accurately adjusting the tens type disk 6 will now be described. 7

Referring to Figures 2 to 6, in the arrangement illustrated therein the controlling plunger 1 of the lever 2 whichserves as a stop for the rotary disk 6 of the tens type element, is connected to said lever in such manner that the effective distance between the two can be varied. T 0 this end, instead of the plunger 1 being directly connected to the lever 2 it is connected to a small supplem ntary arm or lever 24 pivotally mounted on said lever by means of an aide or pin 25 so as to be capable of independent move ment thereon as well as in company therewith. In other words the upper part of the lever 2 constituted by the supplementary arm or lever 24 is formed separately from the lower part of said lever, whereas in thecase of the levers 2a and 2b the upper and lower arms are formed integrally (see lever 2a in Fig. 1). liieans are provided to enable the supplementary arm or lever 24 to be changed in position on the main lever 2. For this purpose the arm or lever 2 L has fast with it or with its axle an arm 26 (Figs. 3, 4-, 5) provided with a lateral projection 27 which has contactual engagement with a stepped cone 28 slidable along the carrier shaft 3. The stepped cone is movable to different positions along the shaft by a hand operated lever 29 (Figs. 2 and 3) fitted with a fork 30 which operates in a circumferential groove in the cone, so as to bring any one of its steps 28a under the projection 27 and thus vary the position of the arm or lever 24 on its main lever 2. The stepped portions of the cone lead from one to another by inclines 287) so that the projection 27 can ride up and down in a ready manner. A spring 31 connectcd to the arm or lever 24 and to a pin 32 on the weighted arm 9 of the lever 2 holds the projection 27 in contact'with the cone. The hand lever 29 (Fig. 2) is fulcrumed by means of a pin 29a upon a bracket 33 attached to the adjacent end frame 1 and may move over a quadrant 34; attached to or formed on said bracket and marked to indicate the different positions. Further said lever 29 is provided with a projection forming a pointer and may be fastened in its difierent positions along the quadrant by a spring controlled pin, catch or other device. Conveniently and as shown in Figure 6, the lever 29 is fitted with a sleeve 36 in which a spring controlled pin 37, having a knob 38 attached to it, is mounted for projection into one or the other of holes 39 (Figure 2) in the quadrant according to the position of the lever. The release and movement of the hand lever can thus be effected by means of the knob. The effect of moving the stepped cone 28 along the shaft 3 is to turn the supplementary lever 24 on the main lever and thereby alter the point of connection of the plunger 1 in relation to the carrier shaft '3 and the opposite end of the main lever 2. By reason of the aforesaid construction the levers 2 and 2e constitute, in eifect, a single lever, so that upon actuation of the shaft 3 said levers 2 and 2 1 normally rockas a whole to move the plunger 1 connected thereto towards and from the disk 100. The effect of moving the stepped cone 28 along the shaft 3 is to turn the supplementary lever 24: relatively to the main lever and thereby alter the point of connection of the plunger 1 in relation to said shaft and the opposite end of the main lever. For example, when the cone is moved from the position shown in Figure 2 to that shown in Figure 3, the lever 24.- is turned from its initial position indicated by dot and dash lines in Figure 5 to that represented by full lines in the same figure. Thus, ac cording to the adjustment of the cone 28 the plunger 1 is moved to a greater or lesser extent toward the stepped disk 100, and the lever 2 for arresting the tens type disk 6 is correspondingly advanced as required.

Through the operation of the lever 29, the range of marking operations'by the marking machine is widened, through a change in the range of marking by the tens type blocks, adjustment of the lever 29 resulting in a shifting of the range of marking operation by the said tens type blocks.

The arm 26 is shown split and fastened on the axle 25 by a screw 40 so that it and the lever 24- may be adjusted on the lever 2.

In this marking machine, which is espeof th indicator meansand the pointer shaft remain locked in the indicating position of the pointer until they are released at the will of the operator. The cam disk 100 which is operated from the pointer shaft is also locked in position to control selection of ap- It will be recalled that in this type propriate type blocks by which the measurement indicated by the pointer may be stamped on the work by the type blocks. Immedi:

ately after the cam disk 10c comes to rest in its type selecting and controlling position the operator ti in the clutch of the marking inachhc .i open tion being immediately followed by a partial rotation of the shaft 3 under control of the cam 23, the shaft movin the d' ction f the arrow in Fig. l.

Rotation or the shaft in the direction indicated permits the weighted levers 9 to operate the piungers 1, la, 16 and their respectively connected levers 2, 2a, 2?), moving the plung rs toward their respective cams 10. tlhviously the plunger-s 1, la, and 1?) may move to the oft in Fig. 1 such distances as may be determined by the cams carried by the cam disk iUc. it is to be understood that the amount of rotation of the cam disk 19c deteri'nincs the height of each cam at a point opposite to the end of each plunger 1, 1a, 1b. in this way the cams 19 control the setting and hence of their connected limnediately following the he plunger-s and their connected the type disks 6 are caused to rotate i "h in the dire tion of the arrow in Fig. 1, each disk rota'tir yutu one of the pins 5 carried eoy stir es the end of its associated lever a or :20, which lever thus acts as a stop for setting the type disk 3 in selected position. Since the type disks 6 are yieldingly driven from the shaft 8 the latter continues to rotate, making a complete revolution, thus insuring that ltll disk 6 will finally reach rd position. During the rotation of the b the type elements 7' are moved along with and are finally brought into selected position below a type wheel 50, as shown in Fig. 8 of the drawings. While the type blOLilZS are in selected position, a work su n xort 3 shown) is caused to lift the work to i it against the type whereby proper characters are marked on the work. 'lhe work lifting mechanism may be of the type di. closed in United States Letters Patrad l lo. 1173.312. granted Feb. 29, 1916 on :lfPlltft'lilOll of t}. A. Schettler, or it may be of the construction and arrangement shown i applicants amending application, Serial 3.3"?330 med Slept. 22, 19:26. If the lot or inches or other pieces of work are ra l as size. so mucn so that the pointer l or means for the measuring mato must make more than a complete revicn on the dial in order to indicate the of the individual skins, then the oper- F'. at the controlling means for g 5 so as to take care of the "iping' by the tens type blocks by ncing the plunger 1 in a dired controlling cam 10 on the cam l. 105. .he result being that the lower end ot the connected lever 2 is set a correspond ingly greater distance away from the center of the type disk 6 so that it will contact with and serve as an abutment for one of the pins 5 nearer the periphery of the disk 6. This nae-ans the disk 6 travels farther in the rotation of the shaft 8 (than it would without the adjustment) before it is brought to rest by contactof one of its pins 5 with the abutment end of the lever 12 and hence that a higher type block moved into selected position in accordance with the measurement indicated by the pointer. This setting of the plunger 1 tween the brackets for which purpose it is provided on opposite sides with flanges 43 (Fig. 7) which mate with corresponding grooves 44 in the brackets. When in position the trough is fastened by pins 45 passed through corresponding holes in the brackets and flanges, although screws or other suitable means may be employed. The trough may, of course, be otherwise attached so as to be removable. Ink feeding rolls 46 and 47, indicated in outline in Fig. 8, may be mounted in the trough in any convenient manner permitting of easy removal for cleaning purposes.

.An inking roller 48 is carried at its opposite ends by two arms or levers constructed so as to enable said roller to yield during its movement a feature of the arrangement be ing that the roller 48 is controlled by cams which cause it to travel in a substantially straight path in contact with the faces of the set types, as will be presently described. The supporting arms are attached to a shaft 49' on which are rotatably mounted the type wheels 50 which (in conjunction with the disks 6 hereinbefore referred to) carry the type elements 7. This shaft 49 is rocked to actuate the inking roller 48, as will be hereinafter described. Conveniently and as shown, spring-controlled supporting arms or levers are employed and each arm comprises a hearing 51 (see particularly Figures 9 and 10) for the reception of the corresponding end of a spindle 52 which carries the roller 48, and a rod 53 screwed into said bearing 51 and slidable through a bearing 54 pinned on the shaft 49. A compression spring 55 is interposed between the bearing 54 and nuts 56 screwed on the free end of each rod 53. Each bearing 51- has on one side a cam roll 57 which by means of the spring 55 is held in contact with the peted by proper manipulation of the lever ocular with an inwardly curved part 58a (Fig.

9) with which the set or selected types, represented by dot and dash lines 7 a are'brought into alignment under working condition. The convexly curved parts of the cams 58 hold the roll 48 away from contact with the type blocks so that only the type block in marking position is inked. When the shaft 49 is actuated the inking roller 48 swings concentrically from its initial position a (Figure 8) until the roll 57 reaches the part 58a of the cam 58 whereupon the roller 48 is caused to travel in a substantially straight line in contact with the set types 7 a as representedin Figure 9. The movement of the roller is continued to approximately the point 6 (Figure 8) whereupon, it is immediately reversed and' returned torts mltl'al position at a.

The inking roller .48 is'made adjustable in relation to the cam rolls '58so that its contact with the types can be regulated, this being accomplished in the illustrated construction, by adjustment of the bearings 51 on the rod 53 (Fig. 9). v

To enable the inking roller 48 to be readily removed from its supporting swing arms, each of the bearings 51' is formed with a slot 59 (Fig. 9) through which the spindle 52 may be passed, and is fittedfwi'th a bushing slidable endwise on the spindle 52 into and out of the bearing. The bushings 6O slide along the inking roller spindle 52 and when inserted in the bearings 51 keep said spindle in position. Upon the bushings 60 being withdrawn endwise the spindle 52 will pass through the slots 59 and can thus be removed from the arms. The bushings 60 preferably remain upon the spindle 59. so as: to be removable therewith for which purpose the ends of the latter may extend a suitable distance from the bearings and be flared as indicated in Fig. 10 to prevent complete removal of the bushing therefrom. Each bushing 60' has a pin 61 therein and the corresponding bearing 51 is provided with a gap or groove 62' to permit of the passage of the pin into the bearing for engagement with a circumferem tial groove, 63 in the latter to prevent displacement of the bushing under normal working conditions. In its initial position the inking roller 48 engages with the ink feeding roller 47 through anopening 64 in the trough 41. The shaft 49 has fast thereon agear'wheel 65 (Figures 7 and 8.) actuated by a toothed segment 6.6 fulcrumed on a pin 66a in the adjacent end frame 4 and oscillatedby means of a connecting link or rod 67 from a crank disk 68 mounted on a shaft 69 which iscarried' by the end frames 4 and suitably driven rsea491 through the medium ofa single cycle clutch 70 (Fig.7) of any suitable type rendered operative and inoperative in timed relation to the operative movements of the disks 6, the inking roller 48 moving when the disks 6 move, and continuing in movement to ink the stationary type block in marking position before coming to rest at position a (Fig. 8) to receive application of ink from the. roll 47. the crank disk effects, by means of the link 67, segment 66, and gear wheel 65, the necessary oscillation of the inking roller 48 between ink-receiving and ink-applying positions. The shaft 49 is carried by bearings 71 adjustably mounted on the end frames 4. As'shown, the ink feeding roller 46 is driven fromthe shaft 8 by means of'sprocket wheels 7 4 and 75 and a chain 76 (Fig. 7 the roller 47 being driven frictionally by the roller 46.
